Quantum weekly, October 9–16, 2026 | Magic states made on hardware at 40x fewer errors, and the noise a logical gate leaves behind

Google's magic state cultivation runs on Willow at 40 times fewer errors for the 8% of attempts it keeps, and the week's logical gate set tomography on Quantinuum hardware measures what the noise left inside a logical gate is made of.

Quantum weekly, October 2–9, 2026 | 1.03 kHz across a photonic link, and four architectures moved from plans to hardware

A 1.03 kHz photonic link between a trapped ion and a solid-state memory, a simulated code family that wires high-rate codes across planar modules, a 156-qubit processor operated around its defective components, and the three conditional instruments behind the week's commercial headlines.

Quantum weekly, September 25–October 2, 2026 | 0.85 against 0.65, and a classical algorithm for equilibrium

A first strict separation for decoded quantum interferometry, bounds that close the same framework in the regimes its own authors can analyse, polynomial-time classical algorithms for the equilibrium of impurity models, and a trapped-ion result where noise sensitivity outranks gate count.

Quantum weekly, September 18–25, 2026 | Constant space, logarithmic time, heavier checks

Fault tolerance's bill moves into the measurement layer this week, as a proof reaches constant space and purely logarithmic time, heavier checks buy distance in compact codes, and one released stabilizer check makes a logical T gate deterministic.

Quantum weekly, September 11–18, 2026 | 63x, 14.6%, and a threshold for coherent errors

Two proofs give coherent errors a threshold, IBM cuts the sampling overhead of hybrid error detection by up to 63 times on hardware, and IonQ's two application benchmarks are separated from product claims by what remains simulated.

Quantum weekly, September 4–11, 2026 | Quantum scaling moves to the systems interface

IonQ fabricates 256-qubit QPUs at SkyWater, IBM installs System Two at CSCS Lugano, and preprints advance active-volume compilation, 4 GHz photonics, and parity Bell measurements.

Quantum weekly, August 28–September 4, 2026 | Fault tolerance reaches the system interface

IBM's Nighthawk r2, Quantinuum's encoded architecture, learned decoder noise, and neutral-atom compilation each improve a different interface around useful quantum computation.

Quantum Weekly: August 21-28, 2026 | Execution now depends on retained structure

This week's quantum results show how preserving problem, device, and error structure can reduce compilation depth, control recovery time, decoding delay, and QEC overhead.

Quantum Weekly: August 14-21, 2026 | Fault tolerance exposes its execution constraints

This week's evidence shows how cryogenic wiring, neutral-atom compilation, decoder-aware loss placement, circuit generation, and cloud access shape the path from quantum roadmaps to measurable execution.

Quantum Weekly: July 24-31, 2026 | The control layer becomes the benchmark

HRL's cryogenic controller, IBM's verification experiments, Quantinuum's logical QFT, and IonQ's SkyWater integration push quantum progress toward measurable control, trust, and cost.

Quantum Weekly: July 17-24, 2026 | Fault tolerance moves into the systems stack

Google reports a measured Willow control-loop improvement for quantum error correction, while IBM, Infleqtion, PsiQuantum, Quantinuum, and new preprints expose the infrastructure, validation, and resource layers still needed for useful fault-tolerant workloads.
